Referring more in detail to the drawings:

Thereference numeral 1 generally designates a partition system wherein a wall extends between a floor surface 2 and a ceiling surface 3, with the wall having a plurality of pairs of laterally spaced wall-defining panel units 4 extendingbetween upright posts or joint framing members 5 which engage facing edge portions 6 of adjacent panel units 4. Snap-on retainercover members 7 are mounted on the joint framing'members 5 and engage the facing edge portions 6 of the adjacent panel units 4 and retain same in clamping engagement between the 1 joint framing member 5 and the snap-on retainer cover members 7. Ceiling, floor, and-end-edgemembers 8,9, and 10, respectively, engage and position upper, lower, and end edge portions 11, 12, and 13, respectively, of the panel units 4, thereby cooperating with the joint framing members Sand the snap-on'retainer-cover members 7 to position and retain peripheral edges of the panel units 4. The ceiling edge member 8 receives and retainswa resilient clip 14 which cooperates with the ceiling edge member 8 to engage and retain the upper edge portions "of the panel units 4.

Each joint framing member 5 is an extruded member with portions thereof of suitable cross section and the joint framing members 5 are preferably H- or l-sections with substantially parallel-spaced flanges 15 connected by a web portion 16 extending therebetwecn. The flanges 15 each have an exterior face or surface 17 parallel with'thc plane of the wall, and positioned to be engaged by the facing'edge portions 6 of the panel units 4. Each joint framing member 5 has longitudinally extending pairs of mounting ribs '18 and 19 integral with the flanges 15 and extending outwardly from the respective exterior surfaces 17 of each ofsaid flanges 157 The mounting ribs 18 and 19 of each pair are laterally spaced and terminate in outer edge portions 20, with said edge portions of each pair of mounting ribs extending outwardly and inwardly in converging relation,-to-thereby narrow the spacing between the outer edge portions 20 of the laterally spaced mounting ribs 18 and 19.

The outer or free edges of the edge portions 20 of the mounting ribs 18 and 19'are spaced from the exterior surface 17 of the respective flange 15 a distance substantially corresponding to the thickness of the wall panel unit 4, with edges of the facing edge portions 6 of the wall panel units 4 adapted to engage the mounting ribs 18 and 19.

Each of the snap-on retainer-cover members 7 is preferably an elongate structure formed by extrusion, with an elongate platelike cover member 2| and a pair of laterally spaced longitudinally extending fastening structures for engaging the outer edge portions 20 ofthe mounting ribs 18 and 19, with an interference that retains the respective snap-on retainer-cover member 7 in place. ln the illustrated form, the fastening structure is a pair of snap-on ribs 22 and 23 extending from an interior face or surface 24 of the platelike cover member 21 and substantially centered between side edges 25 thereof. The snap-on ribs 22 and 23 are positioned to be inserted between the mounting ribs 18 and 19 and retained in interengagement therewith. 1n the illustrated structure, the snap-on ribs 22 and 23 have diverging portions 26 and 27, respectively, extending outwardly from the interior face or surface 24 and inwardly converging portions 28 and 29 forming the outer edge portions of the snap-0n ribs 22 and 23, respectively.

Exterior surfaces of the outwardly diverging portions 26 and 27 of the pair of snap-on ribs 22 and 23 are spaced apart a greater distance than the distance between corresponding interior surfaces of the outer edge portions 20 of the pair of mounting ribs 18 and 19, whereby-the side edges 25 of the plate member 21 of the snap-on retainer 7 are moved into retaining engagement with adjacent edge portions 6 of the adjacent panel units 4.

It is preferable that the platelike cover member 21 have a slightly arcuate cross section and that the plate member 21 be ofa yieldable material, such as aluminum, vinyl, rubber, or the like, whereby, when the outwardly diverging portions 26 and 27 are retained between the outer edge portions 20 of the mounting ribs 18 and 19, the platelike cover member 21 will assume an arcuate shape having a shorter radius, whereby the opposite side edges 25 thereof clampingly engage the facing edge portion 6 of the panel units 4'and retain same between the exterior surface 17 of the joint framing member flanges l5 and the respective snap-on retainer-cover member 7.

It is noted that the free edges of the inwardly converging portions 28 and 29 of the snap-on ribs 22 and 23 are spaced closer together than the free ends of the edge portions 20 of the mounting ribs 18 and 19, whereby, when the snap-on ribs 22 and 23 are inserted between the mounting ribs 18 and 19, the mounting ribs 18 and 19 are spread apart sufficiently to permit the snap-on ribs 22 and 23 to be inserted therebetween.

The ceiling edge member 8 is a channel-shaped member having a web portion 30 with spaced flanges 31 and 32 extending from opposite edges of the webportion 30. Each of facing interior surfaces 33 and 34 of the flanges 31 and 32, respectively, have aligned serrated portions 35 for engaging and retaining the resilient clip 14, as later described. The web portion 30 of the channel-shaped ceiling member 8 has a recess 36 in an exterior surface 37 of the web portion 30, and is adapted to receive and retain a suitable sealing material 38. The exterior surface 37 of the web portion 30 engages the celling surface 3 and the sealing material 38 is placed in the recess 36 and engages the ceiling surface 3. i

. The resilient clip 14- is preferably an elongate structure formed by extrusion, with an elongate plate portion 39 having opposite edge portions 40 and 41 engageable with the serrated portions 35 in the facing interior surfaces 33 and 34 of the flanges 31 and 32, respectively. The plate portion 39 has a pair of laterally spaced longitudinally extending pair oflegs 42 and 43 extending outwardly from the plate portion 39, and the legs 42 and 43 are positioned to engage and retain the upper edge portions 11 of the panel units 4 between the flanges 31 and 32, respectively.

The legs 42 and 43 are outwardly bowed, whereby said legs 42 and 43 each engage and retain a respective upper edge portion 11 in clamping engagement with the interior surfaces 33 and 34, respectively. In the illustrated structure, the legs 42 and 43 each have outwardly diverging portions 44 and 45 extending outwardly from the plate portion 39, and the legs 42 and 43 have inwardly converging portions 46 and 47, respectively. The legs 42 and 43 each have a gradually reducing thickness from a fixed end of the outwardly diverging portions 44 and 45 toward a free end of the inwardly converging portions 46 and 47, whereby the legs 42 and 43 are flexible, and the portion of the plate portion 39 between the legs 42 and 43 will be moved into contact with an interior surface 48 of the web portion 30 of the ceiling edge member 8 when the legs 42 and 43 each engage the respective upper edge portion 11 of the panel units 4.

it is preferable that the resilient clip 14 be an extruded member of substantially uniform cross section and be of a yieldable, resilient material, such an vinyl, rubber, or the like, whereby the legs42 and 43 will be biased toward the facing interior surfaces 33 and 34 of the flanges 31 and 32 when in engagement with the upper edge portions 11 of the panel units 4.

To install the resilient clip 14 in the ceiling edge member 8, the legs 42 and 43 are moved toward each other to bow the portion of the plate portion 39 between the legs 42 and 43, thereby moving the opposite edge portions 40 and 41 thereof toward each other, to permit same to move past the serrated portions 35 on the facing interior surfaces 33 and 34, :and releasing the legs 42 and 43 allows the opposite edge portions 40 and 41 to move outwardly and be retained within the serrated portions 35 of the ceiling edge member 8.

Thefloor edge member 9 is a channel-shaped member having a web portion 49 engaging the floor surface 2 and flanges 50 and 51 extending upwardly from opposite edges of the web portion 49. The lower edge portions 12 of the panel units 4 engage exterior surfaces 52 and 53 of the flanges 50 and 51,

respectively, and a suitable base member such as a cove base 54 is secured on the lower edge portion 12, to provide a finished appearance thereto.

It is preferable that the base 54 be of a suitable resilient material such as rubber, vinyl, or the like and have a suitable adhesive on the back thereof to engage an exterior or exposed surface of the lower edge portions 12 of the panel units 4 The end edge member 10 is a channel-shaped member having a web portion 55, adapted to engage a vertical surface such as a wall, column, or the like. The web portion 55 has a recess 56 in an exterior surface 57 for receiving and retaining sealing material 58. Flanges 59 and 60 extend outwardly from opposite edges of the web portion 55 and a pair of laterally spaced longitudinally extending legs or ribs 61 and 62 extend outwardly from an interior surface 63 of the web portion 55 and are spaced from the flanges 59 and 60, respectively, a distance corresponding to the thickness of the end edge portion 13 ofthe panel units 4.

FIG. 5 illustrates a modified snapon retainer-cover member 64 mounted on opposite sidesof a-modified joint framing member 65. The modified joint framing member 65 is an ex- 'and preferably 11- or l-sections, withsubstantially parallel spaced flanges 66 connected by a web portion 67 extending therebetwccn. The flanges 66 each have opposed exterior surfaces 68 parallel with the plane of the wall. The modificdjoint framing member 65 has longitudinally extending pairs of mounting ribs 69 and 70 integral with the flanges 66 and extending outwardly from the respective exterior surfaces 68 of each of said flanges 66.- The mounting ribs 69 and 70 of each pair are laterally spaced and terminate in thickened outer edge portions 71, with said edge portions 71 of each pair extending inwardly from facing surfaces 72 of the mounting ribs 69 and 70, to thereby narrow the spacing between the facing surfaces 72.

The free edge of the outer edge portions 71 of the mounting ribs 69 and 70 are spaced from the surface 68 of the respective flange 66 a distance substantially corresponding to the thickness of a wall panel unit 4 adapted to engage said surface 68 at the sides of the pair of mounting ribs 69 and 70.

Each modified snap-on retainer-cover member 64 is an extruded member with an elongate arcuate platclike cover member 73, with a pair of laterally spaced longitudinally extending fastening ribs illustrated as snap-on ribs 74 and 75 extending from an interior face or surface 76 of the cover member 73, and substantially centered between side edges 77 thereof. The snap-on ribs 74 and 75 are positioned to be inserted between the mounting ribs 69 and 70 and in interengagement therewith, with an interference that retains the snap-on panel retainer 64 in place. In the illustrated structure,

the snap-on ribs 74 and 75 each have enlarged outer end por- I tions 78 extending outwardly from exterior surfaces of the snap-on ribs 74 and 75.

Exterior surfaces of the enlarged outer end portions 78 of the snap-on ribs 74 and 75 are spaced apart a greater distance than the distance between corresponding interior surfaces 72 of the enlarged outer edge portions 71 of the pair of mounting ribs 69 and 70 ,'whereby opposite edges of the cover member 73 are moved into retaining engagement with adjacent edge portions 6 of the adjacent panel units 4.

It is preferable that the cover member 73 be of a suitable yieldable resilient material, such as vinyl, aluminum, or the like whereby when the enlarged end portions 78 of the snapon ribs 74 and 75 arepositioned between the outer edge portions 71 of the mounting ribs 69 and 70, the cover member 73 will assume an arcuate shape of a reduced radius, whereby the opposite side edges 77 thereof will clampingly engage the facing edge portions 6 of the panel units 4 and retain same between the exterior surface, 68 of the respective flange 66 of the joint framing member 65.
